No one disputes the fact that oil production will peak some day; the disagreement usually revolves around the timing of the peak. It goes from the most pessimistic Prof. Ken Deffeyes, who believes that peak happened in 2005 to the most optimistic USGS which predicts a peak 3 decades from now.

What good had Wall Street ever done for America? “There must be something useful in there, but it is really hard to see what,” he says. “That’s everybody’s challenge: come up with a clearly beneficial example of financial innovation without mentioning A.T.M.s, and no one can do it."

That's Krugman, but I've heard this from lots of people. I hate bankers as much as the next guy, but what about a clearly beneficial innovation in the car industry without mentioning the seat belt? Yet cars have been consistenly getting faster, safer, and cheaper. What about a clearly beneficial innovation in molecular bioscience? You get the point. All this 'innovation you can point your finger to' stuff I really don't get.

Sorry, I don't know the source for this one - Frag just sent it in an email.

I think the image is more prophetic than funny, even if the dates are probably a bit off. I can see the iBoard in classrooms, in offices and on fridges by 2015, and iWalls (OK, iMat may be pushing it) in high-tech offices and homes by 2020. And everywhere by 2030.

It happens all the time: a guy fails to stop at a red traffic light and crashes into another car, causing massive damage to the vehicle and serious injury to the driver.

Now, imagine a world where the offending driver had no responsibility to pay any form of compensation to the victim, and - no matter how substantial the damage - his only punishment was to have his driving license revoked for three weeks.

Crazy? Welcome to the world of professional sport.

Last weekend, Gunners watched in horror as Aaron Ramsey suffered a terrible injury at Stoke. As a direct result of this, he is likely to be unable to play for months, at immense financial cost to Arsenal and the player himself.

Arsenal is prohibited from filling the vacancy quickly by signing a player from another club, and this could well cost them titles and the financial benefits that come with them. Furthermore, players are a football club's most valuable assets*, and in a very direct sense: Ramsey is worth a lot of money to Arsenal, and the club could have even chosen to capitalize on that by selling him to another club. Ryan Shawcrass caused damage to Arsenal's assets much the same way as having taken a baseball bat and wrecked their offices.

Aaron Ramsey seems to have escaped relatively lightly this time, but of course there's always a chance he will never fully recover, losing out on millions of pounds he has been expected to make as a top-flight footballer. And of course there's the psychological trauma he has to go through.

In econ-speak, this is a classic case of an externality: players and clubs hardly have any incentive to play less agreesively, as they don't have to suffer the consequences of their playing style to the opposing team and its players. Since they don't face the cost, they end up playing more aggressively than is optimal, leading to an inefficiently high level of injuries.

Some people may protest that no player ever intentially injures another, and they would be right. But whether injury is caused intentionally or not is largely irrelevant: it is also the case that no driver ever intends to cause an accident. He merely chooses to take on additional risks by ignoring a stop sign or by driving above the speed limit. Similarly, clubs and players choose to play more aggressively, increasing the probability that any given tackle will cause injury.

FIFA, UEFA and the FA must take action now: any injury caused as a result of foul play should be costed, with the offending club having to pay appropriate compensation to the injured player and his club. This will bring injury rates down, and make the beautiful game better and safer. The current situation is madness.

* Professional sport is really the last example of a labour market where is it OK to buy and sell people; in other areas, such arrangements are strictly illegal: it's called slavery. Even though the status quo is beneficial to both clubs and players, I am deeply perplexed that this is a stable equilibrium, given that all it should take for it to unravel is a single player wanting to declare his contract null and void and bringing the case to a court of law. But this is the subject for a future post.

If present trends continue, the poverty Millennium Development Goal of halving the proportion of people with incomes less than one dollar a day will be achieved on time.

And there's more, from a new NBER paper by Sala-i-Martin and Pinkovskiy entitled AFRICAN POVERTY IS FALLING...MUCH FASTER THAN YOU THINK!(I covered their previous related paper here):

1) African poverty is falling and is falling rapidly; (2) if present trends continue, the poverty Millennium Development Goal of halving the proportion of people with incomes less than one dollar a day will be achieved on time; (3) the growth spurt that began in 1995 decreased African income inequality instead of increasing it; (4) African poverty reduction is remarkably general: it cannot be explained by a large country, or even by a single set of countries possessing some beneficial geographical or historical characteristic.

And there's some lovely graphs too - the style is unappealing, but the content is so sweet it's worth framing them and hanging them on every wall you can find:
